Abstract
An apparatus and method for processing a gray scale in a display device is provided. In the gray scale processing method, a video data is randomly error-diffused by using random coefficients, and the error-diffused video data is dithered by using average picture level (APL) masks, thereby enhancing a gray scale expression and minimizing an error diffusion noise.
